Wikipedia is biased in so many ways. Epstein may be laying out his strategy here, but it's no different than politically motivated moderators removing/updating content based on opinions, and not allowing anyone to change it.
One good thing is that unlike AI, Wikipedia at least allows you to see how an article grew. Yes, for the most part you only see pseudonyms in the edit history, but they represent individual editors with discernible interests and biases, whereas an AI-based 'pedia is a black box.
You can argue with Wikipedians; with an AI-'pedia, not so much.
